Timing Constraints

Timing Constraints

FPGA Designs usually require the proper and complete specification of timing requirements.

Timing constraints may be used to influence and guide the placement of design elements and signal routes between placed elements in order to meet design performance requirements. The two general types of timing constraints are global and path-specific. Global timing constraints cover all paths within the logic design. Path-specific constraints cover specific paths.

Cost:

Duration:
3 full days
Location:
Online
Participant Documents Provided:
Work Book with all presentations. Lab Book to be used for exercises.
Course Objectives:
  • Identify and constrain system clocks.
    The timing constraint process should start with the specification of the global timing constraints for all identified system clocks.
  • Identify and create signal path groups.
    The two primary types of path groups are global and specific. A global group typically includes a group of paths between registers, input paths, and output paths. Specific paths are mostly static or combinatorial paths, paths between clock domains, or multicycle paths.
  • Assign global constraints.
    The general rule of thumb when assigning constraints is to use global constraints for primary coverage of a majority of the design paths. With access to timing constraints, synthesis tools may attempt to optimize the synthesized design to meet the specified timing requirements.
